They have cut or open artery and strong pressure must be used. A tourniquet is the choice.
Many things affect the color of blood when it hits air. The only way to determine what type it is to test it.
If it is spurting, an artery has been cut and there is no time to lose. The bleeding must be stopped very quickly or the patient will die.
You probably cut an atery. Blood has a layer. Pink to red is the levels of danger.
No, you would be "spurting" blood if you cut an artery as that's what carries the blood away from the heart. It has more pressure so it would spurt. However, a vein is carrying the blood back to the heart so there is less pressure, therefore no spurting just an ooze.
the wound is letting off blood
the capilary veins *capilary* veinal "ooze" out
Arterial bleeding/laceration

Arterial blood is under pressure from the action of the heart while venous blood, being on its way back, moves more slowly and steadily. You can tell if an artery is cut by the bright red color of the blood and the spurting action of the blood flow. Venous blood is darker and flows evenly.

There is a lot of dark coloured blood. If it was an artery, the blood would be pulsing out, and bright red. Veins carry blood that needs oxygen back to the heart and lungs so oxygen can be replenished. This is why the blood is dark. Well oxygenated blood is bright red (in the arteries)
